LIRA – spring-tooth harrow

• Blockage-free work of teeth and perfect loosening due to vibration effect.

• The harrow spring tooth with diameter of 10 mm.

• The spring tooth is made of high-quality special steel with special heat treatment: general bulk hardening and additional HFC hardening of ends up to 51...57HRC. Such hardening significantly (in 2…3 times) increases the tooth wear resistance in the working area with high wear, wherein the areas under torque stress are highly strength.

• One tractor driver can fold and unfold the harrow due to design of frame and hitch.

• For quick folding/unfolding the LIRA harrow is equipped with transport wheels with adjustable toe angle.

• Having the chained individual working sections, the LIRA spring harrow perfectly follows any field contours in spite of its wide working width.

• Special agricultural low-pressure tires almost fully eliminate the risk of damage to plants. Also there tires eliminate overcompacting of the soil and don’t leave tracks. Specific thread pattern allows drawing off the dirt and provides smooth running without adhesion of dirt even in overwatered conditions.

• Forged crosses compared to welded ones provide high durability and reliability regardless of “human factor”.
